You’re Not Out of Shape. You’re Out of Hours.

Most people who come to FastFit already train, whether that’s lifting, running, a class, or a trainer. They squeeze it into a calendar that has no room for it.

Eventually the math stops working. An hour to drive, change, train, and shower, several times a week, for results that stalled years ago.

FastFit is built for that math. You get a complete strength and cardio workout in under 30 minutes. It’s coached start to finish, run by clinicians inside a medical gym, and measured so you know whether it’s working.

Your time back. Twenty minutes of whole-body EMS and a sprint ride under eight minutes. That’s the whole workout.

Nothing to manage. No planning, no picking exercises, no wondering what you skipped. You show up, and your coach handles the rest, the way your attorney handles your legal work.

Numbers you can act on. A body composition scan to start, and rescans as you go. If the numbers don’t move, the plan changes.

Built on research, not trends. Both technologies have published trials behind them, and a clinical team runs every session.

Why Am I Working Out and Not Building Muscle?

You’re not lazy. You probably train more than most people you know: lifting, running, a class or two, maybe a trainer. For the last few years, the numbers haven’t moved.

That usually isn’t an effort problem. It’s one of three things.

You’re guessing. A bathroom scale can’t tell muscle from fat from water. Without measuring, you can’t know what your training is actually doing.

Your body changed and your program didn’t. As your body shifts with age, hormones and recovery start driving results more than effort does. What worked at 35 stops working at 45.

You’re training around your weak spots. Left alone, most people train what they like and skip what they need. Chest day happens. Leg day doesn’t.

FastFit fixes the first and third directly. When the second is the real issue, the MedGym medical team takes it from there.

How FastFit Works: Two Technologies, One Session

Step 1: Whole-Body EMS: The Strength Half

Your nervous system limits how hard you're allowed to contract a muscle. That's a safety feature. Whole-body EMS goes around it, so you reach an intensity you can't produce on your own, with no heavy load on your joints. EMS has long been an insider's tool for people whose bodies are part of the job. Tom Holland used it to get in shape for Spider-Man, and Cristiano Ronaldo has said he uses it to supplement his training. That's why EMS is famous. It isn't why we use it. We use it because of the research. In a pilot trial out of Mayo, adding one 20-minute EMS session a week to regular training for 16 weeks improved waist-to-hip ratio, cholesterol, and anaerobic threshold more than training alone.

Step 2: The CAROL Bike: The Cardio Half

CAROL runs a protocol called REHIT: short all-out sprints of 10 to 20 seconds, scaled to you, inside a ride under eight minutes. In the founding trial, adults who had been sedentary did two 20-second sprints per ride, three rides a week. After six weeks their VO₂max, a standard measure of cardio fitness, was up 12–15%.

Step 3: Why Both

EMS builds strength. It isn't a cardio tool, and we won't pretend it is. CAROL covers what EMS doesn't. Put together, you get a 20-minute full-body EMS session and a sprint ride under eight minutes. The whole workout takes less than 30 minutes, door to door.

Strength Training Over 40, Without the Wear and Tear

Getting stronger after 40 isn’t about pushing harder. It’s about training smarter: full intensity, the right dose, and a plan built around your body.

Whole-body EMS lets you train at full intensity while your knees, back, and shoulders carry almost nothing.
EMS has been studied for something that matters more every year: keeping muscle. In a trial of 90 women dieting, the group training with EMS held onto their lean mass while the other groups lost theirs.

That matters now more than ever, because roughly a quarter of the weight lost on a GLP-1 is muscle. EMS is a tool studied specifically for keeping it.
Your first sessions are deliberately dosed low and built up from there, because the muscle stress from a first EMS session is high. That’s the kind of clinical judgment you get in a medical gym.
FastFit is partnered private training: two people, one coach, every session. You get what makes training with someone work: somebody expecting you, and someone next to you pushing through the same set. You still get the attention of a private session, because your coach is splitting focus two ways, not twelve. We’ll pair you with a training partner, or you can schedule with someone you choose. Here’s why working out with others works. There’s nothing to program and no deciding what to do today. You walk in, get set up, and walk out in under 30 minutes with the whole workout done.
Every member starts with an InBody body composition scan showing muscle, fat, and where each sits. Then we rescan. The number either moved or it didn’t. If it didn’t, we change the plan.
